New Superconductors
Abstract
The objective of the program was to study the theoretical and synthetic problems of producing higher temperature superconducting materials. The report consists of four principal sections: A theory section concerned with the calculations of the effective electron-electron interaction in the vicinity of large organic molecules, calculation of Coulomb screening; The extension of band theory methods to linear systems; A synthesis section involved in the synthesis of transition metal linear organo-metallic systems of crystalline or covalently bound structures and with special ligand systems for control of the electronic environment of the metal atoms; An x-ray section for determining the structure of crystalline samples; and An experimental section for determining the material parameters of the prepared materials as functions of temperature and pressure. The synthetic portion includes the work on the so-called Krogmann complexes, cyanine dyes introduced into the glyoxime group, germanium oligomers, rhodium alalogs of the cobalt co-linear trimetallic monomer, SnCoSn, co-linear trimetallic monomers as tin-osmium-tin.
